Marginal note:Definitions

 The following definitions apply in this Subdivision.

CSA C390-10

CSA C390-10 means the CSA standard CSA C390-10 entitled Test methods, marking requirements, and energy efficiency levels for three-phase induction motors. (CSA C390-10)

electric motor

electric motor means a machine that converts electrical power into rotational mechanical power and that

  • (a) is an electric three-phase induction design;

  • (b) is one of the following designs:

    • (i) a NEMA design A, B or C with a three- or four-digit NEMA frame number,

    • (ii) an enclosed NEMA design A, B or C with a NEMA frame number of 56, or

    • (iii) an IEC design N or H with an IEC frame number of 80 or above;

  • (c) has a nominal output power of not less than 0.75 kW (1 horsepower) and not more than 375 kW (500 horsepower);

  • (d) has a cage or squirrel-cage design;

  • (e) is rated for continuous duty or S1 operation;

  • (f) is designed to operate at a single speed;

  • (g) has a nominal voltage of not more than 600 V AC;

  • (h) has a nominal frequency of 50 Hz, 50/60 Hz or 60 Hz;

  • (i) has a two-, four-, six- or eight-pole construction;

  • (j) has an open or enclosed construction; and

  • (k) has an IP code from 00 to 67.

It does not include any of the following:

  • (l) a motor that is cooled by air that is forced over the motor by a fan or blower that is not an integral part of the motor;

  • (m) a liquid-cooled motor;

  • (n) an inverter-only motor; or

  • (o) a motor that is designed to operate continuously only while immersed. (moteur électrique)

explosion-proof motor

explosion-proof motor means an electric motor

  • (a) in respect of which measures have been taken to prevent excessive temperatures and the production of arcs or sparks by the motor; or

  • (b) that is encased in an enclosure that can withstand the explosion of any flammable gas or vapour that might enter it, without being damaged and without transmitting the explosion to the outside. (moteur antidéflagrant)


footless means, in respect of an electric motor, that it does not have feet or detachable feet or that it is not designed to receive detachable feet. (sans pieds)

IEC 60034-5

IEC 60034-5 means the IEC standard CEI/IEC 60034-5: 2006 entitled Rotating electrical machines - Part 5: Degrees of protection provided by the integral design of rotating electric machines (IP code) - Classification. (CEI 60034-5)

IEC 60529

IEC 60529 means the IEC standard CEI/IEC 60529: 2013 entitled Degrees of Protection Provided by Enclosures (IP Code). (CEI 60529)

IEEE 112-2004

IEEE 112-2004 means the IEEE standard IEEE 112-2004 entitled Standard Test Procedure for Polyphase Induction Motors and Generators. (IEEE 112-2004)

integral gear assembly

integral gear assembly means a product that consists of an electric motor and a gear mechanism that are combined in such a manner that

  • (a) the end bracket or mounting flange forms an integral part of both the motor and the gear mechanism; and

  • (b) if the motor and the gear mechanism are separated, only one of them remains intact. (assemblage d’engrenages intégrés)

IP code

IP code means the classification of the degree of protection provided by an enclosure, as set out in IEC 60034-5, IEC 60529 or NEMA MG-1. (code IP)


NEMA MG-1 means the NEMA standard MG 1-2014 entitled NEMA Standards Publication No. MG 1-2014 Motors and Generators. (NEMA MG-1)
